Compressed platform files for VIM3L with mainline kernel

Compressed platform files for VIM1S with vendor kernel 5.4.y

Compresses platform files for VIM3L with legacy kernel 4.9.206

Serial console

- pin 17 GND  
- pin 18 RX  
- pin 19 TX

Setup VIM3L, baudrate 115200kbps, no hw flowcontrol. Setup VIM1S, bausrate 921600Kbps, no hw flowcontrol.

Using the serial console is worthwhile with mp1, it is an easy way to make quick changes and tests without having to use ssh.
Though not absolutely necessary for normal work, it is a must when testing kernel and u-boot.

SPDIF

- Pin 13 SPDIF  
- Pin 14 GND

I created a short cable with an RCA socket and used a 100R resistor with the signal line (pin 13) just to keep on the safe side.
Works perfectly well with spdif-in on my headphone and main amplifiers.
